   <h2 class="title">简介</h2>
   <p class="para">
    This class represents iterator objects throughout the intl extension
    whenever the iterator cannot be identified with any other object provided
    by the extension. The distinct iterator object used internally by the
    <a href="control-structures.foreach.html" class="link"><em>foreach</em>
    construct</a> can only be obtained (in the relevant part here) from
    objects, so objects of this class serve the purpose of providing the hook
    through which this internal object can be obtained. As a convenience, this
    class also implements the <strong class="classname">Iterator</strong> interface,
    allowing the collection of values to be navigated using the methods
    defined in that interface. Both these methods and the internal iterator
    objects provided to <em>foreach</em> are backed by the same
    state (e.g. the position of the iterator and its current value).

   <p class="para">
    Subclasses may provide richer functionality.
